I have the basics down here: http://autorepair.about.com/od/regul...oil_change.htm - I checked the owners manual and it doesn't tell me how much I should put in. I have a 94 Blazer S10 V6 Vortec engine. Any help?

 

Its 4 1/2 quarts.

 

I'm assuming that it's 4.5 quarts like on mine. The article you linked to - well, the first line of it is BS about letting the engine cool several hours before changing the oil. You want to have the engine run at full operating temperature for about 15 minutes to let the moistureget out of the crankcase and then change the oil while it's warm to make sure it flows out thoroughly. I usually give it about 30 minutes cooling while I raise the truck and collect all the things I neeed to do the change.

 

All the S10-Blazers are 4.5 quarts, although I always put in all 5 quarts.

 

5qts in my Bravada as well to bring it up to the very top of the dip stick.
